Upgrade your under-sink water filtration with the Waterdrop G3P800 tankless reverse osmosis system bundled with two MNR35 remineralization filters. The G3P800 uses 10-stage filtration and has been tested by SGS to help reduce PFAS, fluoride, lead, chromium, iron, nitrate, chloride, large particles and other impurities. It is certified by IAPMO R&T against NSF/ANSI 58 for TDS reduction, NSF/ANSI 42 and 53 for chlorine, taste and odor reduction, and NSF/ANSI 372 for lead-free materials. The system delivers up to 800 GPD and can fill a cup in approximately 5 seconds, while its 3:1 pure-to-drain ratio helps reduce wastewater. A smart LED faucet displays TDS and water-quality status. Each MNR35 uses selected mineral media to add calcium, magnesium, sodium, potassium and other minerals back to RO-filtered water. Each filter provides up to 1,100 gallons or approximately 9-12 months of service, giving the two-filter supply up to 2,200 gallons of combined mineral-filter capacity.
